ClNDER-SIFTER.

SPECIFICATION forming part of Letters Patent No. 310,030, dated December 30, 1884.

Application led April 3, 1984. (No model.)

To ail whom t may concer/1,.-

Be it known that I, JAMns Caramel-Lim., of the town of Oshawa, in the county ot' Ontario, in the Province of Ontario, Canada, have invented a certain new and useful Oinder-Sifter; l

andI do hereby declare that the following is a full,clear,and exact description of the same.

The object of the invention is to devise a einder-sifter in which the ashes from a stove can be thoroughly sifted without creating any dust either in the handling of the ashes or during the actual sifting operation; and it consists in the peculiar construction, arrangement, and combination of parts, as hereinafter more fully described and claimed.

Figure 1 is a perspective view showing my improved dust-proof cinder-sifter, the door of the outer chamber being open and a portion of the said chamber broken away, so as to expose the interior construction. Fig. 2 is a cross-section of the sifter.

A represents the dust-proof case or chamber, having one of its sides,B, hinged so as to forni a door, which door, when closed, shall form a joint perfectly dust-proof.

C is the sifting-box,pivoted within the chamberA,and provided with the crank-handle D, situated on the outside of the chamber A, in order that the box Cmay be caused to revolve without opening the door of the said chamber. rIhe box C is of peculiar construction, it being divided at or about its center by a partition, E, having a hole, e, through it, as indicated. One side of the box C is covered with wire-netting F, of a suitable mesh as to thoroughly sift the cinders intended to be placed within it. On the other side of the partition E the box C is closed, except that a door, G, is provided to allow the insertion ofthe ashpan H. This ash-pan,it will be noticed, is held up tightly. against the partition E in such a position that its contents will fall through the hole e when the box C is turned on its pivot, in order to bring the wire-netting F en the bottom side.

I is an ash-pan placed at the bottom of the chamber A, and intended to receive the ashes sifted through the netting F.

J is a bar extending across the opening in the box A, made for the door B. On this cross-piece galvanized iron or other sheet metal is tacked so as to iiare inwardly and correspond with the flaring metal chutes K, tacked or otherwise fastened on the inside of the box A, as represented. These aring chutes direct the ashes falling through the net ting` F into the ash-pan I.

The foregoing is a description of the general construction of my improved cinder-sifter. The details designed for the satisfactory working of the cinder-sifter will be understood from the following description of the operation of my machine.

As the main principle of my invention is involved in the `fact that the ordinary ashpan of every stove is intended to be inserted into the sifting-box C, it is not necessary,and itis not intended,thata special ash-pan should be constructed for the machine; but it is necessary for the satisfactory working of the sifter that the ash-pan,when inserted into the box, should be held tightly against the partition E, so that the-box G may be turned on its pivot without shifting the ash-pan.

As ash-pans of different stoves vary in size, simple mea-ns must be provided by which the mouth ofthe ash-pan may be held against the partition E. Several plans for accomplishing this end might easily be designed, but as simplicity is the great object of invention the plan illustrated is one which I think will cornmend itself.

rIhe part markedL in Fig. 2 represents a loose board inserted into the box C and supported by the triangular block M,which rests on the bottom of the said box. Vhen the operator brings the ash-pan H to the sifter, he first opens the door B, and, having shot the bolt N so as to hold the box C stationary, he opens its door G and pushes the ash-pan Hin on top of the board L. Vhen the pan H is in proper position, he inserts a wedge, O, between Ithe board L and the bottom of the pan, and as the board L is pivoted on its supporting-block M, the inside of the said board is forced upwardly until it carries the top edge of the ash-pan H against the partition E, the Wedge O simultaneously forcing the other edge of the pan against the said partition. When thus wedged in, the pan Hwill not shift. Hav- IOO 4ing closed the door G and pulled back the bolt N so as to release the box G,the operator closes and fastens the outer door, B,when, by seizing the crank-handle D, he turns the sifting-box C over until its side covered by the netting faces the bottom of the box. and then Working the crank so as to impart a rocking motion to the box C, the cinders, which have been thrown from the ash-pan H through the opening e onto the netting F, are thoroughly separated from the ashes, which fall through the netting into the ash-pan I. The box C is then turned back into its original position, when the sifted oinders fall back through the opening e into the pan H.

In order to insure the complete discharge of the einders thus sifted, the top side of the partition E is made hopper-shaped, as indicated in Fig. 2;.consequently all the oinders on the top side of the partition will naturally fall toward the opening andthrough it into the ashpan I-I, When sulieient time has elapsed to allow the dust to settle, the door B ofthe box may once more be opened, the sifted cinders removed, and a fresh supply inserted.

Vhat I claim as myinvention isl. In a einder sift-er, a box. C, provided with the hopper-shaped partition E, havinga hole, e, and the Wire-netting F, in combination -with the ash-pan H and devices to hold the same against the partition E, substantially as and for the purpose specified.

2. The box C, provided with the partition E, formed with hole e, and having one of its sides formed by the netting F, in combination with the board L, block M, WedgevO, and the ash-pan H, substantially as and for the purpose specified.
